Problems solved by technology

At present, most of the germinated brown rice on the market is made of white rice, which contains lower nutrients than black rice varieties, and has a poor taste. It is not easy for consumers to accept it, making it of low economic value.
The germinated black rice grains are covered by a tough seed coat, which contains a large amount of melanin, which is the essence of black rice, which can beautify the skin, resist aging and prevent diseases, but the seed coat is tough and difficult to release nutrients
[0003] Prior art such as the invention patent with publication number CN104489520A discloses a kind of germinated black rice instant porridge rich in anthocyanin and its processing method, which is processed by screening high-quality raw materials, the cost is high, and the obtained germinated black rice Gamma-aminobutyric acid content increased limitedly

Abstract

The invention discloses germinated black rice and a processing method of a germinated black rice product. A preparation method for the germinated black rice specifically comprises the following steps of (1) rice hulling, (2) rice selecting and impurity removing, (3) soaking and (4) germinating, and then the germinated black rice is obtained. The processing method of the germinated black rice product comprises the following steps that the germinated black rice is taken, black glutinous rice is added, then water and beta-cyclodextrin are added, soaking and cooking are conducted, and the finished product is obtained. Black rice is selected and germinated through a nutrient solution, and a germinated black coarse rice product is obtained, wherein the content of gamma-aminobutyric acid reaches 205 mg / 100g or above and is about 21 times that before germination. Compared with common black rice, the germinated black rice has more functional active constituents, especially the content of the gamma-aminobutyric acid is remarkably increased. Black rice porridge prepared from the germinated black rice and the black glutinous rice is low in cost and high in gamma-aminobutyric acid content and is a green and economical product.

Description

technical field [0001] The invention belongs to the technical field of agricultural product processing, and in particular relates to a processing method of germinated black rice rich in gamma-aminobutyric acid and its products. Background technique [0002] Germinated brown rice is a product composed of young sprouts, bran layer and endosperm obtained by germinating brown rice to a certain bud length through physiological activation process. Its nutritional value is more than 10 times higher than that of ordinary brown rice; especially After germination, the content of some active substances with special physiological functions is significantly increased. For example, the content of γ-aminobutyric acid is more than twice that of ungerminated brown rice, and the content of glutinous rice is nearly three times that of ungerminated brown rice. Germinated brown rice has the functions of anti-oxidation, anti-tumor, lowering cholesterol, lowering blood fat, lowering blood sugar, p...
